Gidrologiches o i i Prognozy, Gidrometeorologicheskoye Izdatel'tvo, TABLE OF CONTENTS FOR "HYDROLOGICAL REPORTS AND FORECASTS' Prof B. A. Apollov Dr Tech Sci The still very :?oung science of hydrological reports and forecasts is growing rapiuly because of the demands of practical engineers in the USSR; moreover, t'..Pre are no handbooks or manuals in this new field. This 500-page textbook attempte ;,o sum up past and present achievements of hydrological reports and forecasts in pre- dicting floods. T'--e book has been approved by the Department of Education of the Hydrometeorological Service as a textbook for hydrometeorological colleges and uni- versities. It is also recommended for engineers and mechanic-hydrologists in their practical work. TABLE OF CONTENTS Introduction 1. Value o..?.
